Weird thing at <bean:define> (probably a tomcat error - I use
tomcat 3.2.1 with the IBM jdk 1.3 on linux):
Here is a sample JSP (copied from the "Bean User Guide"):
----------
<%@page language="java" contentType="text/html;charset=ISO-8859-1"%>
<%@ taglib uri='/WEB-INF/struts-bean.tld' prefix='bean' %>
<bean:define id="last" scope="session" value='<%= request.getRequestURI() %>'/>
<bean:write name="last" />
----------
and here is the result:
----------
Error: 500
Location: /matademo/WEB-INF/jsp/main.jsp
Internal Servlet Error:
org.apache.jasper.JasperException: Unable to compile class for JSP
at java.lang.Throwable.(Throwable.java:96)
at java.lang.Exception.(Exception.java:44)
at javax.servlet.ServletException.(ServletException.java)
at org.apache.jasper.JasperException.(JasperException.java)
... etc. The relevant portion comes here:
Root cause:
java.lang.ClassCastException: java.lang.Object
at javax.servlet.jsp.tagext.TagData.getAttributeString(TagData.java)
at org.apache.struts.taglib.bean.DefineTei.getVariableInfo(DefineTei.java:89)
at javax.servlet.jsp.tagext.TagInfo.getVariableInfo(TagInfo.java)
----------
The offending code seems to be pretty innocent:
// from org.apache.struts.taglib.bean.DefineTei.java:
public VariableInfo[] getVariableInfo(TagData data) {
String type = data.getAttributeString("type");
if (type == null) {
if (data.getAttributeString("value") != null) //**** Line 89
type = "java.lang.String";
else
type = "java.lang.Object";
}
----------
As a temporary measure I give type attribute at bean:define and it works.
----------
<%@page language="java" contentType="text/html;charset=ISO-8859-1"%>
<%@ taglib uri='/WEB-INF/struts-bean.tld' prefix='bean' %>
<bean:define id="last" scope="session"
type="java.lanf.String"
value='<%= request.getRequestURI() %>'/>
<bean:write name="last" />

=========================================================================
OFF TOPIC:
In tomcat 3.2.1 there are a couple of "showstopper" errors (e.g.
getUserPrincipal().getName() overlives sessions and sticks to the
first logged in user, I have illegal access exceptions if I want
to prepare struts bean variable from request, e.g.
<bean:page id="req" property="request" />
<bean:write name="req" property="pathInfo" /> bombs with illegal access
exception
etc.)
=========================================================================
So, the question. Doea anybody experiance these things in other
environments or these are simply Tomcat bugs (in this case I will
report it there). (OFF TOPIC: does anybody know when do we have
a next bug fix release of Tomcat. I'd like to use it, but it's
almost impossible at the moment - Imean: too much workaround).
know when will be a release o
